3D printer filament inventory: spools left, print cost, drying. No spool limit.
Spoolwise keeps track of your 3D printer filament: what's on every spool, what each print
cost, and when a spool needs drying. Free, with no spool limit, no subscription, no account, and
it works offline.
YOUR SHELF
- Every spool with its colour, material, brand, location and how much is left
- Search by colour, brand, label code or location; filter by material or "running low"
- Sort by most recently used, colour, material or what's left
- Add a multipack in one go: four identical spools, four label codes
HOW MUCH IS LEFT, REALLY
- Put the spool on a kitchen scale: Spoolwise takes off the empty spool and corrects what's left
- Empty-spool weights for plastic, cardboard and refill spools, or weigh your own
- Remaining shown in grams, percent and metres (from the material's density and diameter)
- Run-out forecast from how fast you've been using it
PRINT LOG AND COST
- Log a print with the grams or metres your slicer shows; it comes off the spool
- Multi-colour or split prints across several spools
- Cost per print from what you paid per spool, plus electricity per printer if you like
- Edit or delete a print and the filament goes back on the spool
- Success or failed, print time, notes, "print it again"
DRYING
- Drying temperature and time for PLA, PETG, ABS, ASA, TPU, nylon, PC, PVA and more
- Log drying runs; see days since the last one and when moisture-hungry materials need another
- Warns before drying a cardboard spool too hot
LABELS AND LISTS
- Printable QR labels on Avery 5160 (Letter) or L7160 (A4) sticker sheets
- A short code on every spool (S-0042) to find it again in seconds
- A printable inventory list of the whole shelf
STATS
- Filament used per month, by material and by colour
- Spent on prints, cost per print, success rate, value of what's on the shelf
YOUR DATA STAYS YOURS
- Everything is stored on your phone: no account, no cloud, no login to break
- Back up everything to one file and restore it on a new phone
- Export spools and prints to CSV; import spools from a spreadsheet or another app
Works with any printer and any brand: PLA, PLA+, PETG, ABS, ASA, TPU, PA, PC, PVA, HIPS,
carbon-fibre blends and your own materials. Densities and drying times are typical values from
filament makers; your spool's label always wins.
